anisaldehyde

The synthesis cannizzaro of anisyl alcohol from anisaldehyde and formaldehyde was improved with higher yield by solid superbase ( KF/ γ-Al_2O_3) as catalyst and polyethylene glycol as catalytic activator.

对甲氧基苯甲醛与甲醛的Cannizzaro反应合成茴香醇工艺进行了改进。采用KF/γ-Al2O3固体超强碱催化剂、PEG为催化活化剂的工艺路线，提高了产物的收率。

Currently anisaldehyde products mostly prepared by chemical, has serious drawbacks. The newly developed electro-oxidation process and ozonation process, although in environmental issues has been greatly improved, but harsh reaction conditions, equipment for high, industrial difficulties.

目前茴香醛产品主要是通过化学法制备，存在严重弊端，新开发的电氧化工艺和臭氧化工艺，虽在环境问题上得到了极大改善，但反应条件苛刻、设备要求高，工业化困难。

The indirect electrochemical oxidation of anethole to anisaldehyde with Ce~ ( 4+)/ Ce~ ( 3+) as redox mediator system was studied in this thesis.

本文主要研究了以茴香脑为原料，用Ce~（4+）/Ce~（3+）作为氧化还原媒质，间接电化学氧化合成茴香醛。
